, Our invention relates generally to ma chines for handling ice cream and the like and ,particularlygto a machine for filling cartons or. boxes with ice cream. It should I -be understood of "course that-whileourinkiventionis particularly adapted for-ice cream, i

sit is not-limitedthereto, being equally useful in other arts.

' It is the practice in this art to fill paper or i card-board cartons of various convenient V siies with ice cream in semi-frozen condition, the. filled cartons then being placed under refrigeration to complete thefreezing operai tionfbefore delivery to the usersi It has been 151a real problem in filling these containers to exhaust the'air from thecontainers duringthe I' fillingthereof in orderto permitsuch filling atihigh speed and'by automatic or semi-automaticmachinry; There have been various more or less complicatedsuctiondeviceswith telescoping parts, a tried out but if success- 'fulat all, have not'succeededin increasingthe speed by 1 which theconta'inersmaybe provide an apparatus for filling'cartons withsllghtly beyond thereduced end 2 of the ice cream' at a high rateof speed, the operation of the'apparatus being "practically automatic.

The reference numeral '1 indicates an outer tank or large enclosure provided at its lower end With a threaded, restricted open end 2. The

upper end of this tank 1 is curled out w wardly as at 3 and the upper surface of this curled edge is provided with abacking 4 upon which is adapted to rest the upper 5 of an inner container 6, the

thetank 1 except at the point of the packing 4, where an air-tight connection prevails. A

g V cover .7 provided with air vents 8 closes the filled greatlybeyond that of filling by hand. 25 I The pri'mary object of our invention'isto open upper ends of the tanks. The inner container 6 is also provided with a restricted lower end 9passing through andprojecting outer tank 1 and being xThis inner container 6 is adapted to contain the ice cream 10 in semi-frozen; condition and when empty may be removed by liftingthe same out of the outertank 1 A still further object isto:- provide such a at the top and whereupon a full inner container 6 may be lowered into'position.

Screwed onto the restricted lower end 2 of; the outer tank 1 isa support 11 adaptedto e locked in position on said restricted end end 9 ofthe inner container6;

-The underside ofthe support 11 is provided with a dove-tail groove 14: adapted to provided withspaced opening 13 in'the support lland' adapted to regisslide 15 are provided with upstanding stop members 18. 'removably' secured torthe slide I placed thereby and forced the carton and between the tanks land 6,

. gagement therewith, accurately position the v within the tank 1, such as'salt,

23 engage when insert'edin the hollowbosses 1 17) and opening 16 or 17 (Whichever the case may be) directly in alignment beneath the opening 13 in the support 11. It will be understood also that by removing one of the stop members 18, the slide 15 may be removed entirely from the dove-tail groove 14 in the support 11, for cleaning, etc.

Projecting downwardly from the underside of the slide 15 at points aroundthe openings 16 and 17 are hollow bosses 20 and 21.

The bore of these bosses is slightly greater than the diameter of the openings 16 and 17 thereby providing shoulders 22 against which theupperedges of the cartons or containers 20 and 21. These shoulders 22 are so positioned as to bring the upper edges of the cartons into alignment with the lower edges of the openings 16 and 17 'It will'be understood that the cartons 23 are of such size with respect to thehollovi bosses 20 and 21 that when the same are inserted therein, they remain 'frictionally held in position.

It will be noted with reference to Figure 1 that the lower end of the inner container 6 stops flush with the upper surface of the slide 15 in order to permit the free movement of such slide tovand fro to alternately bring the openings 16 and 17 therein in alignment with such end and with the opening 18 in the support. 1

Opening at a suitable point into the space: between the outer tank 1 and the inner container'6 is a pipe or hose able vacuumor suction device Interposed in this vacuum line isa catch basin or receptacle 25 adapted to receive the deposit of foreign substances which may be drawn from dirt, or other matter which may be scraped off of the outer surface of the inner container 6 as the same 7 is lowered into the outer tank 1.

It will be-observed with reference to Figure 1 that the vacuum or suction through the pipe 24: exerts itself completely around the outer side of the inner container 6 and, due to the spacing of the restricted end-9 thereof, from the end 2 of the outer tank, includes in its'afi'ected area theopenings 11 an d 16 (or the carton 23, which latter, dueto such suction, is firmly held against the shoul- V der 22 in the hollowboss 20.

Obviously this suction tends to'create a vacuum within the carton 28 andaround the 23. 'Obviouslyalso, as the carton-'23 fills up the carton; is dis:

with ice cream, the air in upwardly out of J Qaleading to a suit- Figure 1 and where it is carried off through the suction pipe 241.

It will be understood thatduring the filling of one carton 23, for instance in the hollow boss 20, another carton 28 may be inserted in To the hollow boss 21 and when the first one has been filled, the slide 15 is pushed to the right J in Figure 1, to bring the second carton into position for filling. While this oneis being filled, the loaded one is removed and an empty one put in its place. It has been found by actual experience that the cartons 23 become filled by this apparatus almost instantaneously. Therefore, the speed of the apparatus is limitedonly by the speed of the 0 port 11. The engaging surfaces between the V supportll andtheslide 15 are of course ma-; g5 chinedsmooth and to a perfect sliding fit so that there can be no leakage between these two elements. Y f The space 26 between the two openings 16 and 17 in the slide 15v is slightly greater tham the diameter of such openings so that when the slide is moved to a position suchas shown in Figures 3'and 4:, the opening 13 in the V support 11 is sealed as is the lower end 9 of the inner container locked in said position, if desired, by means of a pin 27 engageable through registering openings 28 in the support 11 and slide 15.

It is sometimes desired to fill these cartons with two kinds of ice cream and the Idifi.'-"100 cation shown in Figure 5 illustrates how this can be accomplished with our apparatus. In this figure, the same parts are shown as in are indicated bythe same reference characters. vided a second inner container 29 adapted to contain a different kindor flavor of ice cream than that contained in thecontainer 6. c This innermost container 29 likewise has a re- 7 stricted lower open end 30. passing througl @3110 and spaced from the endfl9 of the container 6 andterminating flush with the lowertend of'such container. Obviously, therefore, in operation, the suction above described, will I cause the ice creamfrom vboth the inner containers 6 and29 to "be-discharged into the carton 28, the ice cream'from the containerf6 surrounding that from-the container 29.

Fromthe' foregoing, it willbe: clear that g 1 wehave devised a simple and efficient appa 6. The slide '15 may b e-.5195
